Finn has a YouTube channel called [Finn The Wild](https://www.youtube.com/channel/UCQhqom_46OESnmu9eeNFCCQ), and wild he most definitely is! In this video, he's taking extreme to a whole new level by completing crazy challenges in the freezing cold. Finn's adventures include jumping out of a tree and running through the snow — all in nothing but his underwear. Why? We have no idea...all we know is it looks *painful*.
